What's in the box?

Upgrading from a limited 6-channel radio to a far more versatile 8-channel radio with computer functionality on a budget doesn’t mean you have to settle for less than the best. The Spektrum™ DX8e gives you the unbeatable response of DSMX® technology, the simplicity of Spektrum AirWare™ firmware as well as many other features you won’t find on other “budget” radios.

Your growing skills deserve a transmitter than can keep pace. The DX8e comes equipped with the programming you need, no matter what you fly. And because it’s based on the same Spektrum AirWare firmware used in most other Spektrum transmitters, you can share model setups with just about any Spektrum user you meet.

With the flexibility 8-channels delivers, it’s exciting to consider all the options many modern aircraft can accept. Aircraft with flaps, retracts and SAFE® select can now all be flown to their full potential. With its extra channels at the ready, you can consider adding lights to a switch or a simulated bomb drop option. Try out what extra flight modes and mixes can offer, play with gain settings on the AS3X® system—all without sacrificing premium functions you enjoy like flaps, retracts or dual-ailerons and elevators.

The built-in telemetry feature can give you real-time information on things like battery voltage, signal quality, motor temperature and more.* You can also program alerts that let you know when specific telemetry values reach or exceed limits you define.

*Requires telemetry sensors and a telemetry-enabled receiver.

Wireless Trainer Link

The wireless trainer link gives instructors the option to wirelessly ''buddy box'' with another DSMX/DSM2® transmitter. Once bound to another transmitter, ModelMatch™ technology will allow the DX8e to re-link without having to go through the bind process again.

WITH WIRELESS TRAINER LINK, YOU CAN:

Wirelessly 'buddy box' with another DSMX®/DSM2® transmitter when teaching someone to fly

Assign gimbal functions to a second 'camera' transmitter when flying a camera drone so you can focus on avoiding obstacles and maintaining visual contact while someone else lines up the shot

The DX8e’s patent-pending gimbal design lets you change gimbal spring configurations simply by moving a slider switch on the back of the transmitter. No tools are required. Just select the spring configuration that matches the mode you are using and model type you are flying. That’s it.

The slider switch is protected by a hinged cover and slider-lock that prevents you from changing spring configurations accidentally.

Front-Access Gimbal Adjustment

Access to tension, ratchet and travel adjustments for each gimbal is conveniently through the front—no disassembly required. There’s nothing to it. Even mode conversion adjustments are accessible. To create the perfect feel, just lift off the rubber access cover and make a simple adjustment.

250+ Model Memory

The enormous capacity of the DX8e’s on-board memory means you will rarely, if ever, need to juggle models between transmitter memory and your SD card. The model memory menu is easy to navigate too. Only memory slots with model settings saved to them will appear. You won't have to scroll through empty slots or move models around if one is deleted.

DSM2 is the 2nd generation of Spektrum DSM technology and remains a premier 2.4GHz choice even today. Using the same superior wideband DSSS foundation that all Spektrum technology is based on, DSM2 consistently provides faster response and more precision than most non-DSM 2.4GHz protocols.

DSMX is a natural evolution of DSM2 technology that is the result of several years of development, optimized for pilots and combining Wideband DSSS and Frequency Agility. It builds on what has come before and takes DSM to the next level of robustness, reliability and efficiency without leaving current DSM2 users behind. DSMX represents the world's first wideband, frequency-agile 2.4GHz signal protocol and the most advanced spread spectrum RC technology to date.

The foundation DSMX is built on is the same foundation as DSM2™ - the superior on-channel interference resistance and coding gain of wideband DSSS. Compared to the wideband signal of a DSM2 or DSMX™ system, the narrow-band signal of other 2.4 transmitters is more likely to suffer crucial data loss in the event of on-channel interference. Think of wideband 2.4 as a river and narrow-band 2.4 as a stream. It takes much more interference to stop a river than it does to stop a stream.

The big reason wideband is so robust is coding gain. Essentially what this means is that the unique coding in a DSM2 or DSMX wideband signal allows it to be heard well above the noise of surrounding 2.4GHz signals without requiring any more power. In fact, a Spektrum wideband signal can achieve as much as 3X the range of its narrow-band competition using the same amount of power.

For the most part, yes. DSM2 transmitters are forward compatible with DSMX receivers and DSMX transmitters are backward compatible with DSM2 receivers. And because DSM2 and DSMX share the same wideband DSSS foundation, all Spektrum users will enjoy superior range, speed and precision whether they're using DSM2 equipment, DSMX equipment or a combination of both. The only exception is the DXe which is DSMX-only and not compatible with DSM2 receivers.

Yes, but DSM2 users who rarely, if ever, fly in big events or other "noisy" 2.4GHz environments may find the DSM2 equipment they have now is all they will ever need. The difference DSMX makes is only apparent when hundreds of 2.4GHz systems are in use at once. To see if your transmitter is eligible for the DSMX add-on, please visit horizonhobby.com, click on the “radios” tab, and select “DSMX addons” for more details.

A resequencing of the data a Spektrum transmitter transmits based on the type of mixing you select. This feature helps to sync control services that are connected (such as a swash plate on a helicopter) and is used in radios that have many channels.

The Spektrum™ X-Plus™ 8 module lets you add 8 fully proportional channels to specially equipped Spektrum transmitters and receivers with 10 or more proportional channels. Just plug it into the X-Plus port of a compatible receiver. It is ideal for scale modelers who like to push realism to the extreme with working accessories and lights in addition to the regular control functions. The DX10t and DX18 offer X-Plus.

You should have no problem maintaining control as long as you maintain direct line-of-sight with your model. If you try to fly behind a group of trees or otherwise obstruct your direct line-of-sight, you could be susceptible to losing your control link.

The length of the antenna is on a Spektrum receiver is set and tuned to optimize the range and performance of the receiver. We do not recommend altering the length of the antenna on any Spektrum Receiver.
